Cannot import KiteConnect

NishithSavla edited February 15 in Python client
I have a script where I'm using KiteConnect version 4.2.0 and when I try to import it using,
from kiteconnect import KiteConnect
I get the following error
Traceback (most recent call last):

I have tried all the following solution:
  • Updating all system packages using sudo apt update && sudo apt upgrade
  • Upgrading pyopenssl using pip install pyopenssl --upgrade
  • Installing libffi with sudo apt-get install libffi-dev
Can anyone please help me with this?

    sudo apt-get install libffi-dev
    I think, you need to install both libffi and libffi-dev.
    Maybe you can try :
    sudo apt-get install libffi6 libffi-dev
